WORCESTER — Ian McCoshen scored with 8:44 left and top-seeded Boston College beat UMass-Lowell 4-3 on Sunday in the NCAA Northeast Regional final to reach the Frozen Four for the 11th time in 17 years.

Boston College (28-7-4), seeking its fourth NCAA championship in seven seasons, will faces East Regional champion Union in the national semifinals April 10 in Philadelphia.

Boston College's Johnny Gaudreau, the nation's leading scorer, set up goals by Bill Arnold and Kevin Hayes. Ryan Fitzgerald also scored for the Eagles.

Thatcher Demko stopped 29 shots for the Eagles. BC has won NCAA titles each of the three times (2008, '10 and '12) it advanced from Worcester.

Evan Campbell, Michael Kapla and John Holmstrom scored for UMass-Lowell (26-11-4), the region's second seed and Hockey East tournament champion.

McCoshen, skating in from the left point, beat Connor Hellebuyck with a wrist shot after taking a pass from defenseman Teddy Doherty. McCoshen banged his stick on the ice to get Doherty's attention.

Campbell's goal, which caromed in off BC defenseman Scott Savage, gave the River Hawks their first lead of the game, 3-2 just 43 seconds into the third period. Campbell was skating toward the side of the net and sent the puck out front.

Just 21 seconds later, Fitzgerald took the puck at center ice and split a pair of defenseman before tucking a backhander behind Hellebuyck.

Boston College, the Hockey East regular-season champion, moved ahead 2-1 when Arnold scored off the rebound of Gaudreau's shot with 2:26 left in the second period, beating Hellebuyck with a wrist shot. Gaudreau broke into the offensive zone, his shot was blocked by defeseman Zack Kamrass, but bounced directly to Arnold, who kicked it from his left skate to his stick.

The River Hawks tied it when Holmstrom banged in his own rebound with 1:16 left in the second.

The Eagles grabbed a 1-0 lead when Gaudreau set up Hayes 12:57 into the game. Gaudreau, who had three goals and three assists in BC's 6-2 semifinal win over Denver on Saturday, took a loose puck at center ice, broke in deep down the left wing and slipped a pass across the crease to Hayes, who one-timed it past Hellebuyck.

UMass-Lowell tied it on Kapla's power-play goal late in the period when he fired a wrister from the point that found its way through a group of players and slipped past Demko's glove.

Gaudreau had a unique shot on goal early in the second. Charging to the net looking for a rebound, the puck bounced into the air — too high to play with his stick or glove — so he used a soccer-like header to get it on goal from the edge of the crease.

EAST REGIONAL

UNION 3, PROVIDENCE 1

Page 2 of 2 - BRIDGEPORT, Conn. — Max Novak had a goal and an assist and top-seeded Union beat Providence to advance to the Frozen Four for the second time in three years.

Mat Bodie and Matt Hatch also scored for Union (30-6-4). The Dutchmen, who lost in the 2012 national semifinals to Ferris State, are ranked No. 1 in the nation for the first time in program history.

Nick Saracino scored with a little more than 5 minutes left in the third-period for Providence (22-11-6).

WEST REGIONAL

ST. CLOUD STATE 2, NOTRE DAME 1 (OT)

ST. PAUL, Minn. — Nic Dowd scored with 2:39 left in overtime to give St. Cloud State a 4-3 victory over Notre Dame on Saturday night the NCAA West Regional semifinals.

Dowd, a Hobey Baker Award finalist who leads the Huskies with 22 goals, fired a wrist shot from the left circle that beat Steven Summerhays high.

"At this point, any shot's a good shot," said Dowd, whose Huskies (22-10-5) will play top-seeded Minnesota on Sunday for a spot in the Frozen Four. The Gophers beat Robert Morris 7-3.

St. Cloud State was outshot 36-12 in regulation before turning the tables on the Irish with a 16-6 advantage in overtime. Huskies coach Bob Motzko said their slow start might have been caused by too much rest — St. Cloud State lost in the first round of the NCHC playoffs and had two weeks off before Saturday's game.

MIDWEST REGIONAL

NORTH DAKOTA 2, FERRIS STATE 1 (2OT)

CINCINNATI — Connor Gaardner scored off a rebound 1:28 into the second overtime Saturday night, sending North Dakota to a 2-1 victory over Ferris State and its 20th trip to the Frozen Four.

The seven-time national champions got an at-large berth and the fourth seed in the Midwest Regional when rival Wisconsin knocked off Ohio State for the Big Ten title. North Dakota (25-13-3) then knocked off top-seeded Wisconsin in the NCAA tournament semifinals.

Sophomore goalie Zane Gothbert had a career-high 44 saves, and Gaardner scored soon into the second overtime for North Dakota's first trip to the Frozen Four since 2011.

Ferris State (29-11-3) had several chances at the end of the third period and overtime, getting off nearly twice as many shots on goal.

Ferris State opened the scoring in the second period on Cory Kane's goal, and North Dakota tied it in the period on Stephane Pattyn's power-play score.
